(Clockwise from top left) Madhan Balasubramanian, Jennifer Gallagher, Stephanie Short & David BrennanDentist migration is an emerging policy issue in the
Asia-Pacific Region (the region includes the WHO South-East Asian Region and
Western Pacific Region). While migration is a human right1, and considered
essential for global development, it can also lead to brain drain in developing
and poorer countries2. To date, there is very little understanding
of the dentist migration issue and analysis of its impact on oral health
systems and dental workforce development in this region3. This
commentary aims to provide an overview of the dentist migration issue in the
Asia-Pacific Region.

Why do dentists migrate?

Oral health is integral to general health and dentists aim
to maintain and improve it in accordance with the ethics of the profession and
within the scope of their education, training, and experience. The choice of
dentistry is an at­tractive career option for school leavers4,
requiring at least five years of dental education and training before they can
practise. The high educational invest­ment and technical skill-sets possibly
makes dentists an obvious candidate group for migration.

The reasons for dentist migration are complex5,
and include the lure of better remuneration, professional development, career
growth, better working and living conditions. Political and economic forces
also influence the decision to migrate.

Dental workforce in the Asia-Pacific

It is estimated there are about 1.5 million dentists
globally6. The Asia-Pacif­ic region is home to a quarter of these.
India, Japan, China, and the Philip­pines contribute to about 80 percent of the
dentist workforce in the region. Overall, there are about 10
dentists for every 100,000 people in the region. Some middle-income countries in the region
have for many years deliberately trained more healthcare providers that can be
absorbed into the domestic healthcare system. For example, the number of
private dental col­leges in India increased from 55 in 1990 to 259 in 20137.
Nevertheless, with more than 20,000 dentists graduating every year, India still
faces a scarcity of dentists in the villages. Whilst similar issues exist for
doctors and nurses, the disparity is more marked for dentistry8.

High-income countries such as Japan, Australia, New Zealand,
Singapore and Republic of Korea have more than 30 dentists for every 100,000
people. However, many low- and middle-income countries in the region have less
than five dentists per 100,000 people. Pacific Island countries such as Papua
New Guinea, Kiribati and Vanuatu have some of the lowest dentists-to-population
ratios in the world. Geographic inequalities and maldistribution of dentists
(between urban and rural areas) is common in almost all countries in the re­gion.

Migration patterns

The predominant migration pattern in the region is the
movement of dentists from middle- to high-income countries. Countries with
shared historical and cultural ties, such as being part of the Commonwealth of
Nations, can influ­ence migration9. Dentists from India, Malaysia,
Sri Lanka and Bangladesh are more likely to migrate to high-income countries in
the region also hav­ing a Commonwealth connection (Australia, New Zealand,
Singapore and Brunei).

The existence of several bilateral agreements between
countries (and dental councils) influences the free movement of dental
personnel. For ex­ample, Australia and New Zealand have mutual recognition of
dental quali­fications; and an Indian dental degree is accepted for
registration to practice in Malaysia. Also trade liberalisation agreements may
be agreed regionally, possibly leading to improved migration flows among health
professionals. A good example is the Association of South East Asian Nations
(ASEAN), fol­lowing the creation of the ASEAN skills recognition framework10.
However, many of these regional agreements are at the very early stages, and
national dental councils maintain strict protocols on the recognition and
assessment of overseas qualifications.

The case for a regional hub

A major gap in understanding the dentist migration issue is
the lack of relia­ble data to support policy decisions, highlighting the
importance of workforce surveillance, research evidence and political advocacy
on the migration of dentists11. Many poorer and developing countries
in the region lack suitable health/dental workforce surveillance systems, such
as workforce censuses or surveys. There exists very little reliable information
on key issues such as numbers, geographic distribution, and practice activity
patterns. Most organi­zations involved in understanding migration issues focus
on doctors and nurs­es, and dentistry is relatively neglected in research and
development.

Migration data are key to support policy analysis of health
personnel migra­tion12. A minimum requirement is data on inflow,
outflow and stock of dentists, reasons for migration, career plans, career
history, job satisfaction and cultural adaptation issues are essential to better
understand the influences on migra­tion and for policy development.

A regional logistics record could improve
research and data on dentist migration issues and broadly other dental
workforce issues, so as to provide ideas and evidence to underpin policy
decisions13. Such a hub could possibly be a part of an international
dental workforce and/or oral health inequalities agenda. Research intensive
university/academic structures that can provide a sustainable long-term
solution to dental workforce research and capacity building in the Asia-Pacific
Region offer a logical avenue to build the platform. There also exists a strong
case for global organizations (such as FDI World Dental Federation, International
Association for Dental Research and the World Health Organization) to
incorporate dentist migration and dental work­force strengthening agenda as
part of a broader vision of oral health inequali­ties and to enable them to
play a more proactive role in the Asia-Pacific region.
